The formula for finding the Volume of square pyramid is given by :
where a is base edge and,
h = height.
We are given in the figure,
base edge = 18cm
Height =12 cm
So plugging these values in the formula for volume , we have
On solving we get ,
Volume of square pyramid = 1296 cm³.
So first option is the correct choice .
Answer:
A- control group

cant see the whole graph so can't really answer.
to answer this you should locate the x-coordinate on the x-axis and then go up and check wat is the collaborating y-coordinate that touches the line. and continue on.
